        Berkeley DB currently disallows the <a href="../api_reference/C/dbopen.html#open_DB_TRUNCATE" class="olink">DB_TRUNCATE</a> flag to
        the <a href="../api_reference/C/dbopen.html" class="olink">DB-&gt;open()</a> method on VxWorks because the operations this
        flag represents are not fully supported under VxWorks.
    </p>
      <p>
        The <a href="../api_reference/C/dbsync.html" class="olink">DB-&gt;sync()</a> method is implemented using an ioctl call into
        the file system driver with the FIOSYNC command. Most, but not
        all file system drivers support this call. Berkeley DB
        requires the use of a file system that supports
        FIOSYNC.

            The demo program should be built in a manner very
            similar to building Berkeley DB. If you want different or
            additional BSP build specifications you should add them by
            following the directions indicated in <a class="xref" href="build_vxworks.html#build_vxworks_intro6x" title="Building for VxWorks 6.x">Building for VxWorks 6.x</a>.
        </p>
        <p>
            The demo program can be downloaded and run by calling
            the entry function <span class="bold"><strong>dbdemo</strong></span>
            with the pathname of a database to use. The demo program
            will ask for some input keys. It creates a database and
            adds those keys into the database, using the reverse of
            the key as the data value. When complete you can either
            enter EOF (control-D) or <span class="bold"><strong>quit</strong></span>
            and the demo program will display all
            of the key/data items in the database.

        <p>
            The Berkeley DB utilities can be downloaded and run by
            calling the function equivalent to the utility's name. The
            utility functions take a string containing all the
            supported arguments. The program will then decompose that
            string into a traditional argc/argv used internally. For
            example, to execute <a href="../api_reference/C/db_stat.html" class="olink">db_stat</a> utility on a database within an
            environment you would execute the following from the
            windsh prompt. Obviously you would change the pathname and
            database name to reflect your system.

        <p>
            The Berkeley DB Replication Manager component is
            available on Vxworks 6.x because it provides support for
            TCP/IP sockets and POSIX 1003.1 style networking and
            threads. You must build Berkley DB for Vxworks using the
            command line. Prior to building Berkeley DB, ensure you
            set appropriate values for the variables specified in Step
            1 of <a class="xref" href="build_vxworks.html#build_vxworks_intro6x" title="Building for VxWorks 6.x">Building for VxWorks 6.x</a>. To use
            Berkeley DB Replication Manager, <code class="literal">netLib</code>
            and <code class="literal">ioLib</code> must be present in the
            Vxworks image.
